 is used as polishing material in Tokyo. 



97. Chrysocolla. 



This mineral is found in several Japanese copper mines, 

 but a specially interesting specimen is from Hisan-ichi near 

 Arakawa in Ugo. On the surface of its amorphous mass, 

 are found numerous small chrysocoHa pseudomorphs with 

 curved faces, looking like a rhombic crystal in Poo. od P. od Pœ ; 

 angles on the upper edge of the dome and the front edge of the 

 prism measure about 140°. The pseudomorph is about 0.4 cm. 

 wide. 



98. Axinite. 



Two essentially different varieties of axinite are found in 

 Obira in Bungo. 



Kikuchi has described dark-brown to dark-violet crys- 

 tals from Okuradani in Obira. They form druses and aggre- 

 gates of individuals, attaining a length of 2 cm. and 

 characterized by the combination of following faces : — 



coPœ, ooP^, oP, co'P, œP,' P,' 'P, i'V 2T'œ, s^Ps, 

 o,P6, besides, 2V œ and 2'P ^, which are but rarely ob- 

 served. 



This variety is not sharp-edged nor thin tabular in habit ; 

 but rather prismatic with striations on the broad face of P and 

 on various prismatic faces. Kajiura's analysis gave the following 

 result :
